Head-body separation device with guide function

Abstract

The invention provides a head-body separation device with a guide function, comprising a guide assembly and a thrust assembly, wherein the guide assembly and the thrust assembly are arranged in a cylinder body and respectively comprise a guide push rod and a thrust spring which are arranged in the cylinder body; the front end of the guide push rod extends out of a front cover of the cylinder bodyand is used as a thrust end pushing against the head, namely the rear end of an aircraft, a piston which is matched with the inner diameter of the cylinder body is arranged at the rear end of the guide push rod, a compression spring which is arranged in a cylinder body chamber is arranged between the piston and a rear cover of the cylinder body, and the rear cover of the cylinder is fixed on the inner wall of a separation body through a base. The maximum stroke L of the guide push rod is smaller than the maximum compression amount 5mm-10mm of the spring. The maximum stroke L of the guide pushrod is greater than the maximum length H about 5mm-10mm of a protruding structure on the rear end surface of the aircraft. The front end of the guide push rod is sunk in a groove at the rear end of the aircraft.

Description

technical field [0001] The invention relates to a head-body separation device with a guiding function, in particular to a head-body separation device with protrusions on the rear end surface of an aircraft, belonging to the technical field of head-body separation structures, and specifically a head-body separation device with integrated separation and guidance functions device. Background technique [0002] In order to transport the aircraft to the predetermined airspace, the launch vehicle usually uses a multi-stage engine connected in series. After the rocket is separated step by step and reaches the predetermined airspace, the aircraft and the carrier are separated from the head and body. In order to reduce the quality of the aircraft and increase the firing range, usually some structural parts and the attitude control engine of the aircraft are stretched into the separation body (installed on the rear end face of the aircraft). In order to reduce the impact of the sepa...

AI Technical Summary

Problems solved by technology

The separate design of two sets of mechanisms (separation mechanism and guide mechanism) inevitably increases the structural quality of the aircraft and the separation body, reduces the range of the carrier, and cannot meet the head-to-body separation requirements of long-range aircraft
